ORE AND COAL WASHER.

To all whom it 'may concern:

Be it known that we, HENRY W. FALKER, FRANKLIN SGHULTZ, and JOHN F.WAGNER, citizens of the` United States, said FALKER .residing at Ashlandand SCHULTZ and WAGNER at Tamaqua, in the county of Schuylkill and Stateof Pennsylvania, have invented certain new and useful Improvements inOre and Coal Washers, of which vthe following is a specification.

This invention relates to ore and coal Washers and more particularly tothat class in the washing tank, said pan having its rear end .stepped soas to impart a rolling movement to the coal over the bed of slate andthus permit the ready discharge of the coal at the front of the machine.

A further object is to provide a novel form of gate or cradle forautomatically controlling the discharge of slate'from the jig pan to thewashing tank, the construction of the jigger being such as to permit theseparation of both `cube and flat or flake slate. V'

A still'furthe'r object of the invention is generally to impr ve thisclass of devices so as to increase their utility, durability andefficiency.

Further objects and advantages will appear in the following description,it being' understood that various changes in form, proportions and minordetailsl of construction may be resorted to within the scope of theappended claims.

For a full-understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor eifecting'the result, reference is to be had to the following'description Yand accompanying drawings, inn'hieh Figure l is a sideelevation partly 1n section of an ore andvcoal jigger constructed inaccordance with'niy invention; Fig. 2 is a top plan view of the same;Fig. 3 isa transverse sectional view taken on the linev 3 3`Specification of Letters Patenti Application filed February 5, l1910.

of Fig'. 1 and looking in the direction of the arrow; Flg. t 1s anenlargedgdetail vertical sectional view of the forward portion of themachine; Fig. 5 is a ldetail perspective View of the stepped end ofthejig pan or box; Fig. 6 1s an enlarged vertical sectional view showingthe manner of retaining the movable screen sections in position on thebottom of the jig'panor'box. 1-

- Corresponding and like parts are referred to inthe-followingdescription and indicated in all the views of .the drawings by the sainereference characters. v

The machine comprises a supporting frame including upper and lowerlongitudinal sills 5 and 6 connected in anysuitable manner by uprights 7and 8 preferably disposed at the opposite ends of the machine,

which engage corresponding eccentric straps 16 carried by suitablehangers or brackets 17 and 18.

Suspended from the hangers 1i' and 18 and mounted for both vertical andhorizontal movement within. the washing tank 9, is a jig box or pan 19adapted to receive the coal and'slush from the feed spout 20, the latterbeing disposed atthe -rear end of the jig box, as shown.

SecuredV to the opposite side walls ofthe jig' box or pan 19, are cleats2l having transversely alined seating grooves 22 formed therein andadapted to receive a plurality of removable screen sections :23, whichlatter vconstitute the bottom of the jig pan. The

position by a a rolling movement to the coal over the bed of slate inthe bottom of the pan and thus to permit the ready discharge of the freecoalthrough a spout 27 at the front of the pan. j

The cleats 21 at the-steps 26 are formed with intersecting lgrooves 28so asto permit the insertion and removal of the screen l sections 29constituting the treads and risers of the steps, it being here notedthat the screen sections forming the tread and riser of each stepoverlap so as positively to prevent accidentaly displacement of saidscreen sections during the movement of the jig 15 p 'The bottom of thejig pan at the front end thereof is provided with an opening 30 throughwhich slate and other refuse is dis-V charged into the bottom of thewashing tank, the discharge of slate through the opening 30 beingautomatically controlled by a rocking gate or cradle 31. The gate orcradle 31 is journaled in the opposite sides of the jig pan and isprovided with terminal angular portions 32 adapted to receive thecorrespondingly angular sockets of governor arms 33.A The arms 33 arecurvedy upwardly and rearwardly on opposite sides of the jig box or pan,there being countenpoises or weights 34 slidably mounted on the freeends of the arms and secured in adjusted position by set screws 35.

Arranged within'the jig pan at the front 5 thereof is an inclined screen36 having an attaching iange 37 and provided with a vertically disposedimperforate portion 38, the

lower edge ofvwhich constitutes a stop for the cradle or gate 31.

The upper surface of the incllned screen 36 is disposed in alinementwith the base of the chute 27 so that as the coal is fed over,

the screen 36 to the discharge spout 27, the

slush and fine particles will pass through the. perforations- 1n thescreen 36 and fall the openingv 30 into the washingA washing tank andcarry the same upwardly through a spout 41 to a suitable point ofdischarge.' Y

vTheconveyer 39 is preferably in the forni of a drag, while the flights40 sweep over a wear plate 42 fastened to thebottom 12 of the tank, saidwear plate serving to prelaterally extendin flange-44 which engag acorresponding ange 45 on a casing sec tion 46, the parts being rigidlyunited .b bolts or similar fastening devices 47 exten ing through thetianges 44'a1id' 45, as shown. The metal at the flange 45 is extendedtransversely across the top of the trough 41 to form a partit-ion 48,thus to divide thel trough into superposedch'ambers 49 and 50, one ofwhich 1s adapted to receive the upper inclined ieg of the conveyer 39,while the otherireceives a relatively short conveyer 51.

An opening 52 is formed in the end wall or partition 10 of the washingtank to permit the passage of the upper leg'of the conveyer 39, while aguard plate .5.3 is secured to the partition above'the opening 52 inorder to house and protect the adjacent end of the conveyer 51. l

Secured to the side walls of the washing tank 9 are inclined' plates 54,which serve to direct the slate, slush and refusefrom'the jig pandownwardly into the path of movement of the liights on the conveyer 39,as best shown in Fig. 3 of the drawings.

Disposed at the upper end of the trough 41 yis a downwardly -inclinedperforated plate "55 which receives the slate from `the conveyer 39- anddirects the same into a suitable discharge chute `56,.there/being achute 57 disposed beneath the erforated. plate 55 to-receive the slushan fine' coal passing through the perforations in said plate.

41 is secu-red An inclined plate ortrough 58 .is alsol preferablydisposed at the upper end f the conveyer 50 for directing the coal onthe conveyer into a chute 59 similar inco'nstructionl to the chutes 56and 57. I

Secured to one of the transverse shafts 14 is a lwheel or pulley 60,which latter may be connected through the medium of a belt with y anysuitable sourceof power, there being'al sprocket wheel :61 secured toeach shaft and connected by vasprocket chain 62ifor trans- `mittingmotion from one shaft to another.'

It will here be noted that the rear hangers 17 are pivotally connectedat 63 with suit. able brackets 6 4 secured to the upper edge of the jigbox or pan, such a construction permitting free oscillatory movement. ofthe pan in both a Vertical and horizontal plane,

while at the same time permitting the hangers 1 7 to be'adjustedlaterally to effect the tension of the sprocket chain 62 when desired.

Keyed or otherwise rigidly secured to one of the transverse shafts l14is a sprocket wheel 64. which engages a sprocket chain 65,

l orages? ,said sprocket-chain passing over a relatively box orjp'an,the slate will gravitate to :perforated bottoni of the pan, while the.of the screen between the: steps and largesprocket Wheel 6G secured tothe adjacent driving roller 67 of the conveyer 50. A gear Wheel 68is'secured to the other end of the roller andjiiieshcs with a corresponding gear `Wheel G9 carried by the upper shaft.

7G of the conveyer 39, there being spaced sprocket Wheels 7l secured tothe shaft for the purpose of vimparting movement to .said conveyor. l f

Thus it'will hesseen that when the material isintroduced through thespout 2G in the coal will roll over the top of the bed of slate .and-bedischarged through the spout 2 at the, end of the pan, in the mannerbefore stated, the vertical movement l'of the pan in the Washing tankcausing the Water to effeet a. thorough Washing of the coal and theseparation of the slate therefrom.

The stepped Aportion 26 of the pan has'u the effect of kicking orfeeding the coal in a forward direction and also has a tendency to trnthe light particles of slate Within the boit and present said slate edgedown,

thus permitting 'the separation of dat or flake slate as Well as cubeslate.

As the slate accumulates on the perforated bottom of' the pan, theWeight of the slate will open or partially open the gate or cradle 31and allow the slate to drop by .gravityv into the bottom of the 'tank 9so as to be taken 4up by the conveyor 39 and deposited on the inclinedplate 55 for deliveryto the slate chute 56, the slush andfine coalpassing throng ,55 for deliveryv to the chute 5T. A

luring the gvratory movement of the jig pan or boit, the free coaldischarged through the spenti?? Will-be deposited upon the convcyer 50and thence be directed bythe in clined plate or chut-e 58 into the coalomite 59 so that the same may he conveyed to a bin or other suitablepoint of discharge.

Having thus described the invention, what is claimed as new is:
